I This invention relates to traction belts, such for example, as traction belts used on automobiles adapted to travel in snow or upon other insecure footing;

r Objects'of this invention are to providea novel form of traction belt in whichthe units are -.each equipped. with transverse chains which engage the tires of the driving wheels and act in the nature ofanti-skid chains to 1g prevent relative slipping between the driving may become lost, the integral yokewill still "hold the successive links and prevent parting of the belt. r V e A further object is to providea traction zobelt having chains as outlined immediately above in which the chains form the normal 1 contacting agent for the tire and support the weight of the tire, thus securing maximum gripping between the tire and the belt.

Another object is to provide a traction belt injwhich'each ofthe'units is provided with a shoe'having a relatively'wide face-to prevent sinking into the snow and in which either an integral or a separate transverse rib is pro- I .30 vided and equipped with a curved lowersurface to engage the snow and secure traction or else to engage an icy surface and; due to'its curved contour, cut lnto the ice and prevent slipping. 1 s r Y i An embodimentof the invention is shown in the accompanying drawings in which units ofthe traction belt; p 1

' Referring to the drawings," it will be seen. that a yoke piece 1 is-provided and is equipped witha depressed central portion and a pair of upstanding outwardly slanting guidingv V wings or ears 2 to guidetheunit'with"refer ence to the driving wheel. This yoke piece fasindicatedat 6" ii Figure 1; is an 'inner 'plan viewr'of one of the g by v p I I t el p'ps urjf ce thsgyoks a I 'Q the-Sh e isprovided with utWaidIy'pr jait arms 3 whichlare integral and are' tl emselves pro} "underside of the; yoke by means of bolts] which' pass through the posts 4;, as shown most clearly 'in Figured. In addition, intermediate bolts: 8 pass through the shoe and the" farms 8 of theyoke' These intermediatebolts carry, thefends of the transverselchainsfl 9. The chains, asf willi be noted; pass through apertures 10 formed in the sidewalls of the vided with integral downwardly extending r linkreceiving posts 4, as'shown .mostclearly' yoke and their end flinksreceive the'bolts 8.

The chains 9 are drawn tight enough between the bolts .8;so that the'central portions of the chains are spaced from the central depressed is portion oftheyo'ke whereby toprovide a greater, gripping actiononthe tire'than if thechains were rigid against thegy'okeflThe chains are free fromattachment'c to the device at other points and are-freeuto adjust them-f selves or move about during the operation'of the device, thus preventing packing of snow "o ic nglon t e er i efl o h elt; a nsur ng a secure g'r1p upon'the tract on wheel;

It is to be noted further that the rib or cleat may be made integral with the shoe instead of separate'therefrom,ifdesired, without departing from the spirit of this invention. Thisshoe or cleatserves a double purpose. It not. only acts in the capacity of a grip uponthe ground but also acts as a very eflicient bracefor the entire shoe .or unit.

Although the invention has beendescnibed in considerable detail, such description is intendedas illustrative rather thanlirnitin'g as the invention may be variously embodied and asthe scope of such finvention'is to bedete'rmined 'asclaimed. r p Iclaim:
